About this grant

The Clean Growth Fund is a UK-focused early-stage climate technology investor. It backs low-carbon innovators with UK-based technology and works hands-on with founders to help them build, scale and grow. The fund's stated thesis is that the net zero economy is an engine of growth, creating better-paid, more productive jobs across UK regions, and that the critical gap is founders able to industrialise climate innovations, supported by investors willing to back them early. The page describes a portfolio spanning power, transport, industry, buildings, circular economy and agrifood. Examples include asset management software for solar plant operators, porous silicon battery anode materials, leather alternatives made from brewery waste, sustainable oils and fats, microbial bioproducts that replace chemical fertilisers and biocontrols, high-temperature industrial heat pumps, reinforcement-learning optimisation for foundation industries, and biosurfactants replacing petrochemical surfactants. The fund's stated first-cheque size is between £500k and £5m. The page is a corporate site and does not set out a formal open call, application form, or assessment process beyond an invitation to get in touch. It also references a Fund II and a sustainability report.
